Re: mfi driver performance too bad on LSI MegaRAID SAS 9260-8i

If anyone is interested, as Michelle Sullivan just mentioned. One problem I found when looking for an HBA is that they are not so easy to find. Scoured the internet for a backup HBA I came across these - http://www.avagotech.com/products/server-storage/host-bus-adapters/#tab-12Gb1 Can only speak

Re: mfi driver performance too bad on LSI MegaRAID SAS 9260-8i

As a side note, we also use this controller with FreeBSD 10.1 but configured each drive as a JBOD and then created raidz zfs pools and that was much faster than to let the LSI do raid5.  Best Doros ___ freebsd-stable@freebsd.org mailing list

Re: mfi driver performance too bad on LSI MegaRAID SAS 9260-8i

Mark, Thanks We have same RAID setting both on FreeBSD and CentOS including cache setting. In FreeBSD, I enabled the write cache but the performance is the same. We don’t use ZFS or UFS, and test the performance on the RAW GEOM disk “mfidx” exported by mfi driver. We observed the “gstat”

Hi, I am working on storage service based on FreeBSD. I look forward to a good result because many professional storage company use FreeBSD as its OS. But I am disappointed with the Bad performance. I tested the the performance of LSI MegaRAID 9260-8i and had the following bad result:
